Fresh Low-Pressure System Develops in Andaman Sea After Cyclone Arnab, Andhra Pradesh May Face More Rain

Yugcharan News / 30-10-2026

A fresh weather system has developed over the south Andaman Sea, a day after Cyclone Arnab crossed the Andhra Pradesh coast, raising the possibility of another spell of rainfall in the State. The India Meteorological Department (IMD) has indicated that the system could intensify into a depression by October 31 and may subsequently influence weather conditions in Andhra Pradesh.

According to the IMD’s Amaravati centre, a low-pressure area formed over the south Andaman Sea and adjoining regions at approximately 5.30 a.m. on Thursday, October 29, under the influence of a cyclonic circulation. The system continued to persist over the same region at 8.30 a.m.

Weather officials said the system was likely to move west-northwestwards and develop into a well-marked low-pressure area over the south Andaman Sea and adjoining Andaman and Nicobar Islands by Friday, October 30. It is then expected to move further west-northwestwards and concentrate into a depression over the southeast Bay of Bengal and neighbouring areas by October 31.

IMD officials in Amaravati have indicated that the developing system could affect Andhra Pradesh. Meteorologists are continuing to monitor its movement and intensity to determine the extent of its possible impact on the State.

IMD Forecasts Further Intensification by October 31

The latest IMD bulletin issued on October 29 described the low-pressure area over the south Andaman Sea as an evolving weather system requiring continued monitoring.

The department forecast that it would first become a well-marked low-pressure area over the south Andaman Sea and adjoining Andaman and Nicobar Islands within the next 24 hours. During the subsequent 24 hours, it was expected to concentrate into a depression over the southeast Bay of Bengal and adjoining regions.

The system’s west-northwestward movement will be an important factor in determining its future trajectory and the areas that could experience rainfall.

Although the IMD has indicated that Andhra Pradesh may be affected, officials are still assessing whether the system will intensify further and how its movement could influence weather conditions along the State’s coast.

The fresh development comes at a time when several districts in Andhra Pradesh and neighbouring States are dealing with the effects of Cyclone Arnab, which brought heavy to exceptionally heavy rainfall to parts of the region.

Heavy Rain Forecast in Coastal Andhra Pradesh on November 1, 2 and 3

The IMD has already forecast heavy rainfall at isolated places in coastal Andhra Pradesh on November 1, November 2 and November 3.

The forecast has drawn attention because the expected rainfall period coincides with the urban local body elections scheduled in the State.

November 1 is the polling date for the civic elections. Despite the possibility of heavy rain, the State Election Commission has decided to conduct the urban local body polls as scheduled.

The possibility of adverse weather could create logistical challenges for voters, polling personnel and local authorities, particularly in areas that have already experienced flooding and damage from Cyclone Arnab.

The authorities will need to monitor local weather conditions and take necessary precautions to ensure that election-related arrangements remain functional.

Meanwhile, the elections for Mandal Parishad Territorial Constituencies (MPTC) and Zilla Parishad Territorial Constituencies (ZPTC) in Andhra Pradesh have been moved to November 5. The urban local body elections, however, will continue to be held on November 1.

The difference in the election schedules means that civic polling will take place while the State remains under the influence of the developing weather system, with further rainfall possible over the following days.

Cyclone Arnab’s Remnant Weakens Over Chhattisgarh and Odisha

While a new low-pressure system is developing over the Andaman Sea, the remnant of Cyclone Arnab has moved inland and weakened.

According to the IMD bulletin, the system was located over south Chhattisgarh and adjoining south Odisha at 8.30 a.m. on October 29. It was centred near latitude 19.4 degrees north and longitude 81.9 degrees east, approximately 40 kilometres north-northwest of Jagdalpur in Chhattisgarh.

The system had moved nearly northwards at a speed of around 18 kilometres per hour during the preceding six hours.

At the time of the bulletin, it was also located approximately 180 kilometres southwest of Titlagarh, 150 kilometres west-southwest of Bhawanipatna, 200 kilometres south of Raipur and 310 kilometres southwest of Sambalpur.

The IMD forecast that the depression would continue moving northwards and weaken into a well-marked low-pressure area over north Chhattisgarh and adjoining northwest Odisha by Thursday evening.

The department said the system was under continuous surveillance by Doppler weather radars at Raipur and Sambalpur.

South Odisha Records Exceptional Rainfall

The weakening remnant of Cyclone Arnab continued to produce intense rainfall across parts of Odisha and neighbouring regions.

During the 24 hours ending at 8.30 a.m. on October 29, widespread rainfall activity was reported over north Andhra Pradesh, northeast Telangana, Chhattisgarh, Odisha, Jharkhand and Gangetic West Bengal.

The IMD reported heavy to very heavy rainfall at several places, with isolated locations in south Odisha and north Andhra Pradesh receiving extremely heavy rainfall of 21 centimetres or more.

South Odisha recorded exceptional rainfall during this period, with some locations reporting totals exceeding 50 centimetres.

According to the figures included in the IMD bulletin, Patrapur in Ganjam district recorded 546 millimetres of rainfall, the highest among the listed locations. Sorada in Ganjam received 503 millimetres, while G. Udayagiri in Kandhamal district recorded 462 millimetres.

Mahendragarh in Gajapati district received 458 millimetres, followed by Sanakhemundi in Ganjam with 388 millimetres and Chikiti, also in Ganjam, with 309 millimetres.

The rainfall figures highlight the intensity of the precipitation associated with the remnants of the cyclone, particularly in southern Odisha.

Other areas also experienced significant rainfall. The IMD reported heavy to very heavy rainfall at isolated places in north Odisha, while isolated heavy rainfall was recorded in northeast Telangana, Chhattisgarh, Jharkhand and Gangetic West Bengal.

Water Release From Baghalati Dam Floods Villages Near Andhra-Odisha Border

The exceptional rainfall in Ganjam district has also affected areas close to the Andhra Pradesh border.

Patrapur, which recorded the highest rainfall in the IMD bulletin, is the location of the Baghalati dam. Water released from the dam has reportedly flooded Ichchapuram and nearby villages on the Andhra Pradesh side of the border.

The flooding has added to the difficulties faced by residents in areas already affected by the passage of Cyclone Arnab.

The situation also underlines the potential consequences of intense rainfall in catchment areas, where water levels and releases from reservoirs can affect settlements located downstream.

Local authorities will need to continue monitoring water levels, drainage conditions and vulnerable settlements as the region deals with the aftermath of the cyclone.

Andhra Pradesh Faces Consecutive Weather Challenges

The developing low-pressure area over the Andaman Sea has emerged as another weather concern for Andhra Pradesh after the impact of Cyclone Arnab.

The State has already experienced heavy rainfall in northern districts, while neighbouring Odisha has reported exceptionally high rainfall totals. Flooding near the Andhra-Odisha border has further highlighted the need for continued monitoring and preparedness.

The IMD’s forecast of heavy rain in coastal Andhra Pradesh between November 1 and 3 is particularly significant because it overlaps with the scheduled urban local body elections.

Although the State Election Commission has decided to proceed with civic polling on November 1, weather conditions will remain an important factor for election management and public safety.

The developing system is expected to move west-northwestwards and intensify into a depression by October 31, according to the IMD forecast issued on October 29. However, officials are continuing to observe its movement before determining the full extent of its impact.

For now, the immediate priorities remain monitoring the new weather system, managing the consequences of Cyclone Arnab and preparing coastal districts for the possibility of further rainfall.

The coming days will be important for Andhra Pradesh as meteorological agencies track the depression’s development and local authorities respond to the continuing effects of heavy rain and flooding.
